POE NVR not providing power to devices

Hi,
Just bought all new equipment through the IPCamTalk store. I'm unable to get the POE NVR (Dahua NVR5216-16P-4KS2E) to provide power through my cat5e to my POE devices.

Things I've done:
  • Connected a 12v power source to the camera, ipcam lights up, connection no problem, and the camera is recognized/feed visible. However, try to use only the POE port, and any camera doesn't get power.
  • updated the NVR to latest firmware
  • swapped/tested/made new cables (cables transmit data without problem)

Is there a property on the NVR to enable POE power output? Or should this be enabled by default? If anyone can help, I'm completely stumped at this point and have researched until im blue in the face.

Thanks in advance!

Devices:
IPC-T5442TM-AS
IPC-Color4K-X
IPC-K42A
NVR5216-16P-4KS2E

When you plug the camera into the NVR do you see if there any lights on the back of the NVR by the RJ45 plug?
 
Negative, there are no lights on the nvr ports to indicate connection, other than the network port. (Tested /w 12v power+rj45 and visible feed)
 
I'm pretty sure these POE NVR's are active out of the box. I believe if you power up the NVR there is a section for the switch, but I don't think there is no control over on / off. I think I have one here I can pull and take a look.
 
What termination did you use for the CAT cables, 568A or 568B or something else? Are they pure copper cables and not CCA, copper clad aluminum? Have you verified every pair and conductor on those cables?

568B, solid copper cat5e cable (link above), i did notice my connector is cat6? (Connector Link) I dont think this is the problem b/c i've also used retail premade cables.
Testing done with - (Tester Link)

The NVR5216-16P 4KS2 has no lights at the ports, so you cant check for indicator lights.
Assuming you have the 4.0 firmware in NVR, from the head menu in NVR check your BPS under Operation.
Is there any traffic on the ports?

BPS with and without 12v power - same network cable. No traffic on the port with RJ45 only.

Strange, Have you try put the camera in a PoE injector or separate switch? It´s more common that the PoE breaks in the cameras..
are you running default 10.1.1.65 and so on for the built in switch?
 
Negative, I don't have anything else POE beyond this NVR.

Although I don't think its the cams? All 3 types (8cams total) (bullet/turret/indoor) don't get power, and work with a 12v. That'd be quite the shipment of lemons.

The NVR assigns the cam IP in the 10.1.1.x range automatically - I haven't manipulated that. The ip isn't the case though imo as it cant detect the cameras w/o power.
 
If the drawing is correct, that has an internal switching power supply; a 120VAC cord powers it like a PC and the PSU supplies 48 to 52VDC for POE, 12VDC for the 3.5" HDD and 5VDC and other voltages as needed by the boards inside.

Just wondering if the POE portion is kaput.
 
Do you have a Poe injector or poe switch you can confirm that it isn't a statistical improbability that every Poe on each camera is shot? But it does sound like bad Poe on the NVR.

No unfortunately, not able to test any other configuration.
 
I opened one up to check -
There is no on /off for the switch or any lights on the back for POE. (noted above)
With these NVR's there is no initialization needed for the cameras, when you plug them in they should show up in the camera list, plug and play.
This is assuming you have the NVR all set up as you said you updated the FW, so my guess still is the switch is out.
 
Take the HDD out and check again.
Normally POE cameras are plug in and play when connect to the POE ports, If still same so the power module on the NVR burned. Will get you a new power module to replace If still same.
 
Hi, how did you solve this issue. I bought a NVR5216-16p-4ks2e from ebay and it has the same problem. The PowerSupply is ok and privides 52V to the PoE Board, but all 16 Ports do not deliver power the cameras nor my poe tester.

Maybe you sold your NVR and now i got it? ;-)

Just chiming in to say my NVR5216-16P-4KS2E also has the same issue where PoE no longer functions.
For the past 2 years all four cameras working perfectly, now all of a sudden no power being delivered. Cameras confirmed working with external PoE supply.
Looks like there's some faulty internals with these NVRs seeing as this is becoming common :(
